Testing of game theory

I got taken down last night when I let my cards make my decisions for me. I was getting short and was almost under the gun (full table), so before the hand was dealt I decided that if I had 4-8c (or a decent hand, of course), I was going to go all-in. I got dealt 46c, so going with my plan, I made my move. 2 callers. Fuck. Both hands were marginal, ATo and something like K9o. Josh was holding the A, and I know he wouldn't have called if he didn't have an A or a painted PP. Justin called with the K9. Anyhow, Josh caught a T on the flop, they checked it down, I didn't improve, and bu-bye.

I still think it was an okay move. If Josh didn't call, I don't think Justin would have. I think Josh's call (giving him 2-1) tipped him towards the call with his mediocre hand. I know that both of them are of the school that thinks any A is good enough for a call against a desperation move by a stack that is less than 50% of theirs, but I don't think they call with anything less than that. I'll have to figure the odds, there - full table where anyone calls w/ pairs 9+ or AQ+, and 2 players that call with Ax. How many times do I get called before the flop?

I'm gonna go to my thinking spot now...
