Default Re: Mason\'s article on bunching

I have to disagree w/masons 33 blind steal situation.

In his blind steal situation, I set it up to give button the top 30% of hands and to give you 33. Your equity is 46%

equity (%) win (%) tie (%)
Hand 1: 46.3419 % 45.92% 00.43% { 33 }
Hand 2: 53.6581 % 53.23% 00.43% { 55+, A2s+, K5s+, Q7s+, J8s+, T8s+, 98s, A7o+, A5o, K9o+, Q9o+, J9o+, T9o }

I set it up to run a second time and this time I made the 3c a dead card to simulate his bunching effect. You still have 41% equity

Board:
Dead: 3c

equity (%) win (%) tie (%)
Hand 1: 41.0308 % 40.59% 00.44% { 33 }
Hand 2: 58.9692 % 58.53% 00.44% { 55+, A2s+, K5s+, Q7s+, J8s+, T8s+, 98s, A7o+, A5o, K9o+, Q9o+, J9o+, T9o }

You're getting 3:1 on your initial call and if we assume a rake of 1 sb, if we took it to showdown we'd be getting 4:3 so our equity would be 42%. Given that 1) the 3c will sometimes still be live for us and 2) rake will not always be 1 sb in different games and 3) Our opponents can be more aggressvie than a 30% attempted to steal blinds, I think this could be a fine call in the bb.

Also note that we can eveluate our position after the flop and that can also improve our equity since we will not go to showdown if the flop is AKx or so.

Calling 33 a fold in the BB is not necessarily correct and I wish it would be expanded on more.
