I'd like to discuss the size of the initial blind and the amount of chips we start with.
With the current settings, a player can go all-in every time he wants:
pre-flop: small + big + call + 60 + call = 180 flop: pot + 180 + call = 540 river: pot + 540 + call = 1620 turn: pot + 190 + call = all-in
Of course, you can try to (and should) defend against such aggression, but I think It is to much. The result is a lot of games that are decided after 1 round.
I did some testing (using 22 bots, with more than 5000 games for each bot) In the default strategy 56%
With slow settings (small blind 5, 10000 chips each) the All-in bot scored 48%.
The average game took 1.5 seconds with the default settings, and 2.5 for the slow settings.
The differences may not look that big, but I as far as I understood, pot-limit should prevent players from going all-in, and that is not the case with these settings.

I'm getting around 60% chance to win against AlwaysRaise in the leaderboard based on a tactic found by simulation. I think that the limit is somewhere between 63-68% chance to win in these settings. I also mentioned to the developers that this is a bit low; such a simple tactic like AlwaysRaise doing so well even against a counter. So yea, I'm with you on this one.

In poker, stacks of 100 big blinds are considered big stacks, for example blinds of 15/30 and starting stacks of 3000 chips. I agree with you that the blinds are currently relatively high compared to the stack sizes, bots only start with 33 big blinds now.
However, the pot limit system indeed allows players to put in a lot of chips in one hand when raising the maximum amount every betting round, I think this is quite normal. In the example you provide, a maximum raise on the river is 1620, so the opponent could put in 2430 chips in total, which equals 81 big blinds. For stacks of 100 BB this is not all-in yet, but it is not far from it.
An always-raise strategy is not easy to cope with, so if other bots play too cautious then it makes sense that this bot is winning quite some games. With very smart bots his static strategy should be exploitable quite well.

I agree - we should start with a larger pot / smaller blind.
Or better yet...
Suggestion to developers:
Can we make the starting pots dynamic? It would add a nice extra variable to the game. If we're in a short-stacked game, we maybe should have an entirely different strategy than for a big stack.

I noticed the starting stack is now 2000 and the big blinds are 20 at the start. I assume that is because of this and other threads on the all in bot odds. So, now we are starting with 100 big blinds. Nice

Yes these settings were implemented last week, we're going to check out how it's working and if it's all good then the competition will go off Beta.
