I think the implied odds here may encourage weaker hands to call. i.e. they have position on you and they think they are getting 7000 if they hit the flop and losing 3500 if they miss yet unless they have a-k they are making a mistake by calling. Surely this is what you want.
I think this is about the weakest hand (in this situation) i would pull this manoeuvre with. Usually i would be all in or fold.
With a short stack in for half his stack in EP, i think one of the last things people are thinking about is implied odds.
If a caller puts 3500 in to win 7000 possibly or can fold if he misses, this is neutral EV. Neutral EV isn't a very good proposition here, calling in with rags for "implied odds" doesn't make any sense here for me. You will miss the flop 2/3 times in poker so if you are calling 3500 3 times, 2 times you will miss and lose 7000, one time you will win and win 7000. If i said give me £1.00 and flip a coin, if it comes down heads i will give you £1.00 back and if it comes tails i will give you £1.00 back, would you ever bother playing with me?
If someone has AK here and calls, do you think they would fold to an all in off the short stack? they are getting 3/1 on their money and they might even be ahead anyway. Plus AK needs to see all 5 cards to maximise its strength, so AK will want to see the river.
Position is also negated here completely against the short stack, we have position in poker to see what our opponents do before us, if we know what our opponent is going to do here (95% of short stacks at least will push in here, the other 5% are just plain crazy betting half their stack to fold on the flop), then position is nothing.
