For more info the blinds were 2k and 4k and the stacks were about me with 45k, SB with 20k, and BB with 8k.

3x the big blind would basically put anyone but me all in pot-committed. I figured unless they had something very strong like a strong Ace they would fold if I raised. If SB had something good I knew he'd push back all in or else he'd fold.

His only outs were the two last deuces. A 6 wouldn't have helped him since I already had 2 pair.
